The demand to use high strength and high performance material because of large span and high rise of building in recent years. As to use of high-strength steel in composite steel and reinforced concrete structures, it remains to be clarified whether the ductile behavior can be ensured, especially when the high-strength steel is used in combination with normal-strength concrete. This paper describes the test results on the elasto-plastic behavior of SRC column using high strength steel, and discusses the maximum strength and the deformation capacity, with the investigation on the applicability of the concept of superposed strength. Experiment and analysis revealed that the behavior of SRC column with high-strength steel was stable. The maximum strength of SRC column was well predicted by the superposed strength theory.
